Problem 651. Functional inputs

Return an n-dimensional array whose elements are the results of a function over a set of vectors.

The (i,j,k, ...n)th element of the output matrix is the results of executing the function on the ith element of the first vector, jth element of the second, and so forth. The function will be passed in, accepts n arguments, and returns a single number.

For example, if the function is:

    minus12 = @(a) a(1)-a(2);

and the inputs are:

    as = [1 3 5 7];
    bs = [0 1 2 3 4];

then the output would be:

    >> gridit(minus12, as, bs)
    ans =
           1  0 -1 -2 -3
           3  2  1  0 -1
           5  4  3  2  1
           7  6  5  4  3
